| From: Tom Horsley <horsley1953@xxxxxxxxx> | That works up to the point where you try to modify the xorg.conf | file. X pays no attention to xorg.conf most of the time these | days. What does work is getting the EDID from the monitor and | stashing it in a firmware directory where you can use it to | force the kernel to override EDID any time anyone asks about it. | | Get edid from currently connected monitor: | | monitor-get-edid > /lib/firmware/edid.bin | | Stick this on kernel options in grub config file: | | drm_kms_helper.edid_firmware=edid.bin | | Now the dadgum kernel will boot with the edid for the | monitor even if it isn't connected at boot time. Wow. I didn't know that but have wished for it. Thanks! Does it work with proprietary AMD and nVidia drivers? Old KVMs didn't pass the EDID information. Newer cheap KVMs only pass it if the computer issuing the query is currently selected. Inexpensive KVMs seem to be a dying technology. Try to find one that does DVI (expensive) or HDMI or DisplayPort. And my latest monitor's EDID capability doesn't quite work with Fedora even without a KVM interposed. Enough works to get the job done. It's a dirt cheap Seiki 39" UHD TV set. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
